retaliatory attacks are no longer sufficient reason to avoid calling an election.
the war against hamas should continue, but israel needs to call an election, now. the outcome might be that netanyahu, who is an old man that should retire, is replaced by somebody that his opponents think is worse. that would be the reflection of the israeli popular will. however, i think you might be surprised at the outcome, which i suspect will return the status quo, perhaps with a rearranged knesset underneath it.
justifications for the war have not ended, but justifications for prolonging democracy have ended, and netanyahu needs to face the verdict of his own people, now.
